FIG. 2 is a cross sectional of another embodiment of the invention. - The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
- Referring to
FIG. 1 , an electricwindow cleaning device 10 in accordance with the present invention comprises anoperating portion 20 with apedestal 21. Ahandle 22 is formed on the top of thepedestal 21 to facilitate the user to hold theoperating portion 20 with one hand. Theoperating portion 20 further includes a plurality ofmagnets 23 which are separately embedded at different positions in thepedestal 21, and the purpose of themagnets 23 will be explained later. Thepedestal 21 is further provided with a plurality of receivingholes 24 with a large upper diameter and a small lower diameter. Each of the receivingholes 24 is provided for accommodating aball 25 which is rollably retained therein by aplug 26 screwed in a large-diameter end of a corresponding one of the receivingholes 24, in such a manner that theballs 25 partially protrude from abottom surface 29 of thepedestal 21 to come into contact with aninner surface 71 of theglass 70 of the window in a point-to-point contact manner, so that the friction force between theoperating portion 20 and theinner surface 71 is reduced so as to facilitate theoperating portion 20 to slide on theinner surface 71. Besides, each of theplugs 26 is provided with asemispherical cavity 27 in one end thereof facing a corresponding one of theballs 25, and a plurality ofsmall steel balls 28 is disposed between thecavity 27 and the corresponding one of theballs 25. Thus, each of theballs 25 can roll in any direction with the aid of thesmall steel balls 28 which have the effect of reducing friction, so that theoperating portion 20 can move freely along theinner surface 71. - Another important part of this invention is a
wiping portion 40 which is magnetically attracted to theoperating portion 20 across theglass 70. As shown inFIG. 1 , thewiping portion 40 includes abase 41 which is the same as theoperating portion 20 and also provided with a plurality ofmagnets 42 andballs 43 at the corresponding positions, so that theoperating portion 20 and thewiping portion 40 can be magnetically attracted to each other across theglass 70 by themagnets inner surface 71 and anouter surface 72 of theglass 70, respectively. Meanwhile, theballs bottom surface 29 of thepedestal 21 and abottom surface 44 of thebase 41 can roll freely along theinner surface 71 and theouter surface 72 of theglass 70, respectively. In the drawings, thereference number 45 represents the receiving holes, 46 represents the plug, 47 represents the cavities, 48 represents the small steel balls, which are the same as the corresponding elements of theoperating portion 20. - The
wiping portion 40 further includes apower mechanism 49 and apower supply device 50. Thepower mechanism 49 includes amotor 51 and areduction gear box 52. Themotor 51 produces a rotational force, and thereduction gear box 52 is connected to the power outputting end of themotor 51 to take the rotational force of themotor 51. Thereduction gear box 52 reduces the rotation speed and increases the torque of themotor 51, and then outputs a rotational kinetic energy via anoutput shaft 53. Theoutput shaft 53 is inserted into a rotary-disc shaft 62 to transmit the rotational kinetic energy to arotary disc 54 connected to the latter. The rotary-disc shaft 62 is rotatably supported on a bearing 57 fixed to thebase 41. A hook and loop fastener (Velcro) 55 is attached to an outer surface of therotary disc 54, so that aduster 56 whose back surface is also provided with a hook and loop fastener (Velcro, not shown) can be attached to therotary disc 54 to clean theglass 70 of the window, and theduster 56 can be removed for cleaning or replacement when it becomes dirty or broken after use overtime. - The
power supply device 50 includes aswitch 58, asocket 59 and abattery 60 which are disposed on thebase 41 and electrically connected to themotor 51 to form a loop which will be closed when theswitch 58 is On and will be opened when theswitch 58 is Off, so as to stop or start themotor 51. Thesocket 59 is provided for connecting an AC/DC convertor (not shown), so that thebattery 60 can be recharged by the AC/DC convertor to supplement the current consumed by thebattery 60. Of course, the loop can also be slightly modified to use the convertor to supply current to themotor 51 and recharge thebattery 60. In a preferred embodiment, thepower supply device 50 further includes apower indicator light 61 which constitutes a part of the loop, and thepower indicator light 61 is turned on or off when theswitch 58 is On or Off, so as to provide a visual signal to let the user know whether the electricwindow cleaning device 10 is turned on or not. - As shown in
FIG. 1 , when the electricwindow cleaning device 10 is in use, the user should wet theduster 56 and spray cleaner on it, then theoperating portion 20 and thewiping portion 40 are magnetically attracted to each other across theglass 70 by themagnets inner surface 71 and anouter surface 72 of theglass 70, respectively, and then theswitch 58 is turned on. When theswitch 58 is On, thebattery 60 is electrically connected to the circuit of themotor 51 to start themotor 51. Thereduction gear box 52 reduces the rotation speed and increases the torque of themotor 51, and then theoutput shaft 53 drives therotary disc 54 to rotate via the rotary-disc shaft 62, and as a result, theduster 56 fixed on therotary disc 54 rotates simultaneously to clean theouter surface 72 of the glass. As the user manually moves theoperating portion 20 which is attracted to theinner surface 71 of theglass 70 of the window, thewiping portion 40 attached to theouter surface 72 will also move simultaneously while performing cleaning operation until the entireouter surface 72 is completely cleaned. - Since the
duster 56 is driven to rotate by thepower mechanism 49, a friction at middle and low speeds will be produced with respect to theouter surface 72 to achieve a quick and efficient cleaning effect. Besides, theoperating portion 20 and thewiping portion 40 can maintain a point-to-point contact with the inner andouter surfaces glass 70 of the window via theballs operating portion 20 and thewiping portion 40 with respect to theglass 70 of the window, so that the electricwindow cleaning device 10 can easily move on the surfaces of theglass 70 of the window and freely turn, so as to improve work efficiency. - As shown in
FIG. 1 , theoperating portion 20 further includes a connectingmember 31 which includes aspherical body 32 and a connectingportion 33. Thespherical body 32 is disposed in aspherical cavity 30 of thehandle 22, and is retained in ahollow cover 34 of thepedestal 21 and rollably locked inspherical cavity 30 by a retaining member, such as a screw (not shown). The connectingportion 33 is formed on an outer surface of thespherical body 32, inserted through thecover 34, and provided for connecting arod 35, so that therod 35 pivoted to the connectingportion 33 by apivot member 36 can be folded with respect to the connectingmember 31. Meanwhile, the connectingmember 31 is freely rollable in thespherical cavity 30, so that therod 35 can be used to move theoperating portion 20, and thewiping portion 40 can also be moved in a simultaneous manner, which is convenient for carrying out the cleaning operation of theouter surface 72 of theglass 70 of the window without the help of a chair or a ladder. Therod 35 can be made of a telescopic rod whose length can be varied, or can be made of more than two rods which are connected by joints, so that the user can adjust the length as desired. The connectingmember 31 is assembled to thepedestal 21 only when it is necessary to use therod 35, and can be removed at ordinary times. - The invention is not limited to the abovementioned embodiments and may otherwise be of different forms. For example, as shown in
FIG. 2 , it can also in the form of the electricwindow cleaning device 10 a which is provided with two wipingportions 40 which are attracted to each other across theglass 70 to simultaneously clean theinner surface 71 and theouter surface 72 of theglass 70 of the window. - While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
